This research could only confirm the 2018 and 2023 census figures directly; an official continuous series for earlier decades was not located within the scope of this research.

3.4 Age structure

⚠️ Data not available No official statistic directly comparing the age structure of the New Zealand-born and overseas-born populations could be identified during this research. The 2023 Census reports an overall median age of 38.1 years (up from 37.4 in 2018), but a breakdown by birthplace could not be directly confirmed in Stats NZ’s published materials. Stats NZ’s “Interactive population pyramid” tool (https://www.stats.govt.nz/tools/interactive-population-pyramid-for-new-zealand/) may support a birthplace breakdown, but this could not be verified during this research.

📊Age structure data broken down by birthplace (New Zealand-born / overseas-born) is planned for a future update.

4. Public finances — net cost

Not publicly available: no official New Zealand study (by Treasury or another public body) quantifying an aggregate net fiscal cost or contribution of immigration could be identified and verified at the primary source. Figures circulating in the press (e.g., amounts in billions of dollars, or shares of tax revenue attributed to migrants) could not be confirmed on stats.govt.nz or treasury.govt.nz and are therefore not included here.

The closest official study (a unique methodology, focused on productivity rather than the fiscal balance) is the report “Immigration: Fit for the Future” (April 2022), commissioned by the New Zealand Productivity Commission (a public body, dissolved in February 2024, with its archives transferred to the Treasury). Its main finding is that immigration is presented neither as the cause nor the solution to New Zealand’s productivity challenges, with a weak and generally positive effect on native wages and employment over the preceding 20 years.

A second, independent official methodology (e.g., a migration module within the Treasury’s long-term fiscal model) could not be located — not publicly available at this time.

📊An official aggregate calculation of immigration's net fiscal cost (or contribution) is planned for a future update. No primary-source calculation comparable to those for Denmark or Australia could be identified for New Zealand.

5. Labor market

Not publicly available: a current, detailed breakdown of employment rates by visa category (skilled, student, work, residence) compared with native-born New Zealanders.

The closest available data are as follows. MBIE’s Migrant Employment Data (monthly, by visa type/sector/region, current to approximately September 2025) measures employment engagement but does not provide an explicit comparison rate against native-born workers. Source: https://www.mbie.govt.nz/immigration-and-tourism/immigration/migration-research-and-evaluation/migrant-employment-data. Stats NZ’s Survey of Working Life (December 2012 quarter, dated data) found that 25% of employed people were born overseas; 36-40% of recent/settled migrants held a bachelor’s degree or higher, compared with 21% of native-born workers; job satisfaction stood at 85.5% for recent migrants versus 76.7% for native-born workers. This data dates to 2012 and no updated version has been found. Source: http://m.stats.govt.nz/browse_for_stats/income-and-work/employment_and_unemployment/snapshot-working-migrants.aspx. NZ Treasury’s working paper “Impacts of immigration on the labour market and productivity” (2024) addresses the topic, but precise figures could not be extracted and verified; this requires confirmation by direct reading. Source: https://www.treasury.govt.nz/sites/default/files/2024-05/pc-wp-impacts-of-immigration-on-the-labour-market-and-productivity.pdf

6. Security / justice

Confirmed: New Zealand does not publish crime statistics broken down by country of birth, citizenship, or visa/migration status. This was verified against the following three official sources, which break data down only by age, sex, and self-identified ethnicity (a category not comparable to migration status): NZ Police, PoliceData.nz: https://www.police.govt.nz/about-us/publications-statistics/data-and-statistics/policedatanz/proceedings-offender-demographics. Ministry of Justice: https://www.justice.govt.nz/justice-sector-policy/research-data/justice-statistics/data-tables/. Stats NZ, Crime & Justice theme: https://www.stats.govt.nz/topics/crime-and-justice/

A methodological caveat to note explicitly: self-identified ethnicity is not a valid indicator of migration status (a New Zealand citizen and a recent migrant may share the same ethnicity category) — these two concepts must never be conflated.

Not publicly available: no official statistical link between migration status and offending can be established in New Zealand.

7. Education

International student enrollments (Education New Zealand) reached 83,425 in 2024, up 21% from 69,135 in 2023. The pre-Covid reference level (2019) was 115,705 — a level not yet recovered. The 2025 figure (provisional, the latest available) was 92,580, about 80% of the pre-Covid peak. The 2024 breakdown by sector was: universities 33,485; schools 18,350; polytechnics (Te Pūkenga) 10,270; private training establishments (PTEs) 10,185; with master’s-level enrollments at 14,695 in 2024, up from 7,945 in 2019. The leading countries of origin were China (~34%), India (~14%), and Japan (~9%). Source: https://www.enz.govt.nz/news-and-research/ed-news/international-student-enrolments-continue-upward-surge

In economic terms, international education-related exports are estimated at NZD 3.6 billion for the year ending December 2024, and NZD 4.52 billion for the year ending September 2025. Export revenue for the 2024-25 fiscal year was NZD 4.3 billion (+22.8%), about 13.6% of total services exports. The government’s stated goal is to double this figure to NZD 7.2 billion by 2034.

8. Housing

The link between immigration and New Zealand’s housing crisis (particularly in Auckland) is heavily debated and is comparable to the Canadian case, providing a useful point of cross-country comparison.

The Reserve Bank of New Zealand (RBNZ), in its Monetary Policy Statement of February 2024, noted that net migration reached about 2.4% of the population annually by late 2023, and observed that “the demand effects of strong migration have shown through into higher rent inflation.” Source: https://www.rbnz.govt.nz/hub/publications/monetary-policy-statement/2024/monetary-policy-statement-february-2024

The RBNZ’s Financial Stability Report of November 2024 (special topic) found that the slowdown in population growth linked to declining net migration is “easing demand for housing” — a reversal compared with the 2022-2023 period. Source: https://www.rbnz.govt.nz/-/media/project/sites/rbnz/files/publications/financial-stability-reports/2024/november-2024-special-topic-1/fsr-special-topic-update-on-housing-market.pdf

As a temporal comparison benchmark, the migration-housing link therefore reversed between 2023 (upward pressure) and 2024-2025 (easing pressure alongside the decline in net migration).

9. Social cohesion

Stats NZ’s general official survey, the General Social Survey (biennial), contains no dedicated module on attitudes toward immigration — a gap that should be flagged explicitly. Source: https://www.stats.govt.nz/help-with-surveys/list-of-stats-nz-surveys/about-the-general-social-survey/

The closest official source is MBIE’s “Public Perceptions of Immigration” survey (waves conducted from 2017 to 2023), commissioned by the Ministry of Business, Innovation and Employment (a public body). The most recent report identified with a stable URL dates to December 2020; a 2023 edition exists but its exact URL could not be confirmed and would need to be located via the program’s homepage. Source: https://www.mbie.govt.nz/immigration-and-tourism/immigration/migration-research-and-evaluation/migrant-and-community-experience-of-migration

Not publicly available: a recent, fully verified government survey specifically measuring the evolution of attitudes toward immigration in 2024-2025. Reports from private/philanthropic organizations (e.g., the Helen Clark Foundation, Ipsos NZ Issues Monitor) exist but are not official sources and are not included here, in line with the editorial charter.

10. Recent political context

Temporary work visa conditions were tightened in 2024 under the Luxon government, following the post-Covid migration peak — to be documented with precise dates.

The precise chronology of the Accredited Employer Work Visa (AEWV) is as follows. On April 7, 2024 (under Minister Erica Stanford), a major reform introduced a new English-language requirement for ANZSCO (Australian and New Zealand Standard Classification of Occupations) skill levels 4-5; a requirement of 3 years’ experience or a level-4+ qualification (except for “Green List” roles or salaries at or above twice the median wage); a reduction of the maximum visa duration for levels 4-5 from 5 years to 2 years, with a mandatory 12-month stand-down after 3 continuous years; an extension of the job-advertising period from 14 to 21 days; mandatory engagement with Work and Income (MSD, Ministry of Social Development); and a minimum of 30 hours per week. The franchisee accreditation category was removed on June 16, 2024. Source: https://www.immigration.govt.nz/about-us/news-centre/changes-to-the-accredited-employer-work-visa-aewv

On December 17, 2024 (with phased implementation through March 2025), a partial easing took effect: removal of the median-wage threshold for most roles, a reduced experience requirement of 2 years, restoration of the visa duration to 3 years for levels 4-5, and a reduction of the temporary labor cap in construction from 35% to 15% (effective January 2025). Source: https://www.beehive.govt.nz/release/securing-skills-and-experience-nz-needs

On December 2, 2024, work rights were restored for spouses of high-salary AEWV holders (at or above 80% of the median wage). Effective November 3, 2025, permitted working hours for student visa holders were raised from 20 to 25 hours per week. On July 1, 2025, the 2,000-visa queue cap for the parent residence visa category was removed (an easing measure, not a new intake opening).

11. Data limitations and biases

⚠️ Limits Under Stats NZ’s 12/16-month rule, migrant status is definitively classified only once 12 months have been observed within a rolling 16-month window of travel history, resulting in a lag of about 17 months before final classification.

Pending this finalization, Stats NZ publishes provisional estimates based on a statistical model, with 95% confidence intervals, revised monthly; the most recent months carry the greatest uncertainty.

This travel-history-based method replaced the former “Permanent and Long-Term” (PLT) measure, which was based on declared travel intentions and which Stats NZ judged to be less reliable.

Data from the Covid border-closure period (March 2020 - December 2022) are unadjusted raw values; seasonally adjusted series prior to March 2020 are fixed and are no longer revised.

The structural absence of cross-tabulated data on country of birth by crime (see section 6), the lack of recent updates to employment surveys by migration status (see section 5), and the absence of age-structure data broken down by birthplace (see section 3.4) are major limitations for fine-grained analysis by migrant category.
